推荐答案

Use a conditional formula to dynamically change the location of a report’s image.

1. Add an image to the report: -> Insert -> Picture
This image will act as a placeholder.
Ensure that the placeholder is the same size as the one that will be dynamically loaded, otherwise, the image will be scaled.

2. Change the image’s Graphic Location:
   ->right click image
   ->select Format Graphic…
   ->select Picture tab
   ->click the conditional-formula button (looks like x+2)
   ->set the formula’s text to the name of the formula or parameter field that will contain the image’s URL
   ->save the formula and click the OK button
   ->Save the report

It worked for me.
